The little stone church on a knoll at the eastern end of the lake is one of the most photographed buildings in Slovenia, and rightly so. The shape — a squat Romanesque tower and a narrow Gothic nave reflected in the lake — is essentially unchanged since the fourteenth century. Inside, the walls are covered in frescoes from three different centuries: Gothic scenes from the 1300s, a Madonna of Mercy from the 1500s, and Baroque additions painted over the top of both.
Opening hours vary by season; check at the tourist office in Ribcev Laz. Even when the interior is closed, the setting on the lakeshore beside the old stone bridge is worth a stop, particularly in early morning or last light when the surrounding peaks turn pink.
